Incredible Prong Set Rhinestone Faux Turquoise 1930s Brooch Pin

This brooch is an absolute work of art. Each rhinestone and piece of faux 
Turquoise has been prong set around the base of the brooch. On the back  is a very long pin that is held with a "c" clasp. Judging by the length of the pin this piece was probably intended for a coat, hat or vintage  wrap. Incredible condition for something is almost 100 years old!
